I'm curious if there's any policy change as since #4027, context-propagation doesn't seem to have made any functional changes, either.

That's a great question. The short answer is: no policy change, this will be an exception though since we were asked by the Reactor team to release 1.1.

The longer answer: Reactor has a policy to support every patch version in a minor they depend on. E.g.: they depend on the latest context-propagation 1.0.x so they want to support it all the way back to 1.0.0. Unfortunately, certain bug fixes in context-propagation 1.0.x were public API changes (adding new methods). Reactor uses these new methods but since they are not available in earlier versions (like 1.0.0), Reactor needs to do some checks (/"hacks") to prevent NoSuchMethodException. They asked us to release 1.1.0 which has these methods so in their new minor release they can upgrade to 1.1.x and remove these checks. If we would not release 1.1.0, their next minor version would still use 1.0.x so they ned to support all the way back to 1.0.0 and keep the checks.
